I am a novice and I am struggling hard to get to the root of my display problem. Whenever I start my laptop Dell Inspiron 8100 , the screen start behaving oddly . It shows random lines all over the screen and I can not do anything . It remains like that. I tried connecting the laptop to external projector and monitor and the same problem repeats so I suspect that problem is not with screen . What I get on external monitor is same as what I see on my LCD: Rubbish . I suspect that problem is somewhere with Video card or somewhere else.
Can you please guide me as to how I should proceed.
Thanks a lot for your help

He suspect that most probable issue could be bad BIOS.
It is very possible your bios got corrupted some how. The only way to fix this would be to get a new motherboard. Is your dell still under warrenty?
